Howdy fellas, I have my Dad's 1986 Ford F-250HD XL 2WD 6.9L/C-6.
It has pretty bad air intrusion (Surges idle, dies, won't rev) until I hook another line to the return output and put my thumb over it and put pressure on the system. I replaced the line that goes from the lift pump to the frame, and right now I have a clear line that goes between the hard line to the lift pump and the hard line to the filter head, not getting very many bubbles anymore, if anything on occassional itty bitty teeny tiny little bubble. And after I plug the line, if I unplug it and put it in the diesel can or if I put the OEM line back on it will slightly surge at idle but it will still rev, but will die or try to die when put in gear. Really getting discouraged on these IDIs and loving my own 460 EFIs instead lol.
